Resumen:
Abstract From 1998 to 2000 we used radio telemetry to
study habitat use by greater rheas Rhea americana in rural
areas. Captive-born greater rheas preferred pastures to
grasslands and did not use crops. No differences in
habitat use were found between wild and captive-born
greater rheas. Wild individuals preferred pastures,
showed less preference for grasslands, and did not use
crops. Rheas used pastures and grasslands for nesting
but they did not use crops. No differences in nesting
success was detected between these habitats. Our results
show that agroecosystems that include grasslands and
pasture production would strongly contribute to the
conservation of this species. However, poaching must
be controlled to ensure long-term persistence of wild
populations of greater rheas.
